Definitions
- Aqueous liquid compositions for example hand dishwashing compositions, generally need to have a specified viscosity behavior to be acceptable to the consumer.
- Many liquid compositions should have a viscosity behavior which provides pourability and ease of dissolution in water in order to be considered consumer acceptable, particularly in liquid cleaning products like hand dishwashing liquid.
- the dissolution rate of the liquid in water is desired to be rapid so that foam generation is not delayed, since foam is a signal to consumers that the detergent is high quality. Pourability and dissolution are in part linked to liquid viscosity.
- EP 0 222 557 discloses a liquid detergent composition containing 5-50 wt% of an anionic surfactant, 0.1-12 wt% of a polymeric surfactant comprising a hydrophilic and a hydrophobic group, 0-10 wt% of a stabilizing nonionic surfactant, 0-10 wt% detergency builder, 0-15 wt% alkanol and 20-90 wt% water, wherein the composition has a viscosity of greater than 100 cps.
- US 2005/0272619 discloses a detergent composition having A viscosity of at least 700 cps, measured using the standard Brookfield viscometer method at 20°C, and comprising 0.1-3 wt% of an organic salt, inorganic salt or mixtures thereof and 0.05-10 wt% by of a hydrophobic block copolymer having an average molecular weight of at least 500 and comprising alkylene oxide moieties.
- EP 0 621 335 discloses an aqueous cleaning composition characterized by the presence of 0.01-10 wt% of a quaternary ammonium compound component; 0.1-10 wt% of a nonionic surfactant component; and 3.5-10 wt% of a glycol ether solvent.
- Ethanol is known for uses as a viscosity controller in aqueous hand dishwashing liquid compositions, even though the ethanol does not contribute to enhanced dishwashing performance.
- ethanol tends to be used at high concentrations.
- ethanol comprises 6.5 weight % of the total composition in one known aqueous hand dishwashing liquid composition.
- Such high ethanol compositions may have the desired viscosity profile, but may form an undesired gel phase at temperatures below 0°C, for example at a temperature of -4°C or lower, causing an evident phase separation at the bottom of a bottle containing the composition. This is undesirable for the consumer.
- the high ethanol content increases the cost of the composition. For example, a 6.5 weight % ethanol content may represent about 12 % of the cost of the aqueous hand dishwashing liquid composition.
- aqueous liquid compositions for example hand dishwashing compositions, which can incorporate a viscosity modifier system to provide a viscosity behavior which is acceptable to the consumer yet avoids the gel phase formation and high ethanol cost of known ethanol-containing formulations.
- an aqueous liquid composition for example a hand dishwashing composition, which can provide the combination of a desired viscosity behavior, good anti-gelling performance at sub-zero temperatures and an acceptable production cost.

- an aqueous liquid composition comprising at least one surfactant and water, of a mixture of (a) at least one polyethylene oxide-polypropylene oxide block copolymer which is present in an amount of from 0.4 to 5 weight % based on the weight of the composition and (b) ethanol which is present in an amount of from 0.5 to 5 weight % based on the weight of the composition, for inhibiting or preventing gelling of the composition at a temperature below 0°C.

- a desirable pourable viscosity is provided, together with a robustness against gel formation at low temperatures, in particular sub-zero (°C) temperatures, such as -4°C.
- aqueous liquid surfactant-containing compositions can employ an ethanol content combined with a polyethylene oxide-polypropylene oxide block copolymer content to provide a robust phase stability at sub-zero temperatures while providing the desired viscosity profile of the composition.
- a concentration of the polyethylene oxide-polypropylene oxide block copolymer can be provided. Any increase in concentration of the polyethylene oxide-polypropylene oxide block copolymer is less than the decrease in the amount of ethanol while maintaining the desired viscosity profile, since the polyethylene oxide-polypropylene oxide block copolymer has a greater effect on viscosity, per unit of concentration, as compared to the ethanol. Therefore there is a net cost saving by employing the increased concentration of the polyethylene oxide-polypropylene oxide block copolymer to offset the reduced concentration of ethanol.
- the combination of the increased concentration of the polyethylene oxide-polypropylene oxide block copolymer and the reduced concentration of ethanol was found unexpectedly to enhance the robustness against gel formation at sub-zero temperatures, while maintaining the desired viscosity profile of the composition.

- a polymeric suspending agent can be selected to have a level of crosslinking to give a desired viscosity, pourability, and dispersability to the composition.
- Suspending agents are any material that increases the ability of the composition to suspend material.
- suspending agents include, but are not limited to, synthetic suspending agents, gellan gum, polymeric gums, polysaccharides, pectine, alginate, arabinogalactan, carageenan, xanthum gum, guar gum, rhamsan gum, furcellaran gum, and other natural gum.
- a synthetic suspending agent in one embodiment is an acrylic polymer, such as a polyacrylate.
- compositions of the invention Unless otherwise specified, all percentages are by weight.
- the abbreviation AI refers to the total active ingredient amount of surfactant(s).
- the exemplified compositions are illustrative only and do no limit the scope of the invention.
- a known light duty hand dishwashing composition is shown in Table 1.
- This composition comprised anionic surfactant (an alkyl ethoxylated sulfate AEOS, in particular Na lauryl ether (0.6 EO) sulfate), amine oxide surfactant (in particular lauryl myristyl dimethyl amine oxide), magnesium sulfate and fragrance.

- the amount of Pluronic L44 polymer was 0.3 weight % based on the total weight of the composition and the amount of ethanol was 6.9 weight % based on the total weight of the composition.
- phase stability of this composition was tested at a temperature of -4°C.
- the composition has poor phase stability at sub-zero temperatures.
- the composition of Comparative Example 1 was modified by varying the concentrations of Pluronic L44 polymer and ethanol in the composition of Table 1 and testing the phase stability at a temperature of -4°C.
- the amount of Pluronic L44 polymer varied between 0.3 and 0.5 weight % based on the total weight of the composition and the amount of ethanol varied between 5.5 and 8.5 weight % based on the total weight of the composition.
- FIG. 1 This is a contour plot showing the incidence of gelling at a temperature of -4°C for varying concentrations of the Pluronic L44 polymer and ethanol with the base composition of anionic surfactant (an alkyl ethoxylated sulfate AEOS, in particular Na lauryl ether (0.6 EO) sulfate), amine oxide surfactant (in particular lauryl myristyl dimethyl amine oxide), magnesium sulfate and fragrance shown in Table 1.
- anionic surfactant an alkyl ethoxylated sulfate AEOS, in particular Na lauryl ether (0.6 EO) sulfate
- amine oxide surfactant in particular lauryl myristyl dimethyl amine oxide
- magnesium sulfate shown in Table 1.
- the dark area in Figure 1 indicates compositions which resulted in gel formation at a temperature of -4°C.
- the light area in Figure 1 conversely indicates compositions which resulted in an absence of gel formation at a temperature of -4°C.
- compositions of Comparative Examples 1 and 2 have a high ethanol content, which increases the production cost of the light duty hand dishwashing compositions.
- Example 1 light duty hand dishwashing compositions comprising lower concentrations of ethanol and higher concentrations of the Pluronic L44 polymer were tested to determine the gelling behavior of the resultant compositions at a temperature of -4°C.
- the use of higher concentrations of the Pluronic L44 polymer provides a more stable viscosity profile at higher shear rates, which is desirable for exhibiting stable viscosity during dispensing of the liquid composition by pouring from a container.
- the Pluronic L44 polymer was found to provide a large impact on the viscosity of the composition, with viscosity generally decreasing with higher amounts of the Pluronic L44 polymer, and so increasing the concentration of the Pluronic L44 polymer can provide a stable viscosity profile without an excessive increase in the composition viscosity.
- Example 2 The base composition of Example 1 is shown in Table 2.
- This composition comprised anionic surfactant (AEOS), amine oxide surfactant, sodium chloride and fragrance. Again, this composition additionally comprised varying amounts of Pluronic L44 polymer and ethanol. The amount of Pluronic L44 polymer was varied from about 1.35 to about 1.65 weight % based on the total weight of the composition and the amount of ethanol was varied from about 1.3 to about 1.7 weight % based on the total weight of the composition.
- phase stability of this composition was tested at a temperature of -4°C.
- FIG. 2 This is a contour plot showing the incidence of gelling at a temperature of -4°C for varying concentrations of the Pluronic L44 polymer and ethanol with the base composition in Table 2.
- the dark area in Figure 2 indicates compositions which resulted in gel formation at a temperature of -4°C.
- the light area in Figure 2 conversely indicates compositions which resulted in an absence of gel formation at a temperature of -4°C.
- the concentration of the polyethylene oxide-polypropylene oxide block copolymer is increased.
- the increase in concentration of the polyethylene oxide-polypropylene oxide block copolymer is less than the decrease in the amount of ethanol while maintaining the desired viscosity profile, since the polyethylene oxide-polypropylene oxide block copolymer has a greater effect on viscosity, per unit of concentration, as compared to the ethanol. Therefore there is a net cost saving by employing the increased concentration of the polyethylene oxide-polypropylene oxide block copolymer to offset the reduced concentration of ethanol.
- the combination of the increased concentration of the polyethylene oxide-polypropylene oxide block copolymer and the reduced concentration of ethanol was found unexpectedly to enhance the robustness against gel formation at sub-zero temperatures, while maintaining the desired viscosity profile of the composition.
- the combination of at least one polyethylene oxide-polypropylene oxide block copolymer which is present in an amount of at least 0.4 weight % based on the weight of the composition, and ethanol which is present in an amount of from 0.5 to 5 weight % based on the weight of the composition the gelling of the composition at a temperature below 0°C may be inhibited or prevented.
- concentration of the polyethylene oxide-polypropylene oxide block copolymer e.g. in the Pluronic L44 polymer
